A picture of the field decorated with pig heads had surfaced on Twitter on Wednesday with the caption: "If democracy fails, people become angry and desperate. Welcome to the hell of Eschmarkerveld."

Local media suggests that such a graphic message is not only meant for the migrants, but also the government, which decided to set up the refugee center in September.

When the decision was made the residents of Eschmarkerveld objected to the opening of the refugee camp, arguing they would feel "unsafe." However despite the massive outcry the municipality went on with the planned center.
